The Passaic County exposure is associated with the outbreak in Ocean County, in which a 15th infected person was confirmed with Friday.

Symptoms include rash, high fever, cough, runny nose and red, watery eyes. Measles can cause serious complications such as pneumonia and encephalitis (swelling of the brain), and is easily spread through the air when someone coughs or sneezes. People can also get sick when they come in contact with mucus or saliva from an infected person.
